[Mesa-dev] [PATCH] nv50, nvc0: enable/disable seamless cubemap texturing as requested

In a situation where the seamless setting isn't available on a
per-texture basis (G200+ Teslas, and all Fermis), assume that all
samplers will have it identically set, and enable accordingly.
This fixes arb_seamless_cubemap piglit test on Fermi and Tesla.
